FAG High-grade oil and lubricants bearing high temperature grease

Reasonable use of bearings is the main method to extend their life. The most important thing for rational use of bearings is to do a good job of lubrication of the bearings. To achieve the best lubrication effect of bearings, the selection of grease is critical.

The following aspects must be considered when selecting FAG High-grade oil and lubricants bearing high temperature grease:

1. Anti-rust performance The grease used in the bearing must have anti-rust effect, and the anti-rust agent should preferably be insoluble in water. The grease should have good adhesion and form an oil film on the steel surface.

2. Mechanical stability: Grease will soften during mechanical processing, causing leakage. During normal operation, grease will be thrown from the bearing seat into the bearing. If the mechanical stability of the grease is insufficient, the soap structure of the grease will mechanically collapse during operation, causing the grease to be destroyed and thus lose its lubrication effect.

3. The oil seal is a necessary barrier to protect the bearing and lubricant from external contamination. During the operation of the bearing, no debris or moisture can penetrate into the bearing to prevent damage to it. Correct installation and maintenance is an important factor in maximizing the bearing's service life. At the same time, attention must be paid to the cleanliness of the bearings, the correctness of the bearing selection and the selection of appropriate installation and maintenance tools. In addition, bearings must be protected from contaminants and moisture and must be properly mounted and lubricated. Therefore, the design of the bearing arrangement, the condition of the oil seal, the type of lubricant and the lubrication cycle, and even specialized maintenance all play the same but important role.

4. Mixing greases Never mix incompatible FAG High-grade oil and lubricants bearing high temperature grease. If two incompatible greases are mixed, their consistency will usually become softer, and eventually the bearing may be damaged because the grease is easily lost. If you don't know what kind of grease the bearing originally used, you must completely remove the old grease inside and outside the bearing before adding new grease.

5. The classification of greases is mainly based on temperature and working conditions: Greases can be classified according to their allowable working temperature. The consistency and lubrication ability of grease are affected by the working temperature. Bearings operating at a certain temperature must be selected at the same temperature. Grease with the correct consistency and good lubrication at temperature. Grease is manufactured in different operating temperature ranges and can be roughly divided into low-temperature, medium-temperature and high-temperature greases. At the same time, there is a type of grease called extrusion-resistant or extrusion-resistant and added with molybdenum disulfide. At the same time, additives are added to strengthen the strength of the lubricating oil film.

6. Important factors in selecting FAG High-grade oil and lubricants bearing high temperature grease. If you choose the wrong grease, all measures to prevent bearings will be in vain. It is important to choose a grease whose base oil viscosity can provide sufficient lubrication at the operating temperature. The viscosity is mainly affected by temperature. Effect, it decreases as the temperature increases and increases when the temperature decreases. Therefore, the base oil viscosity at operating temperature must be known. Machinery manufacturers usually specify a certain type of grease, but most standard greases have a wide range of applications.
